[Problem B to be solved by the invention] Recently, the problem of pollution that is thought to be caused by golf courses has been attracting attention. In other words, fertilizers and pesticides used on golf courses leak out and pollute rivers and oceans, seriously impacting seafood farming operations and contaminating water supplies. Reflecting this situation, administrative authorities are beginning to consider taking strict regulatory measures regarding the use of fertilizers and pesticides at golf courses.

By the way, in the above-mentioned conventional water sprinkling system, mere water sprinkling control is performed, and the problem of fertilizers and pesticides is not discussed.

[For production]

Water pumped from water sources such as ponds, rivers, and water tanks is
After being purified by flowing through a filter and mixed with applicable fertilizers, pesticides, biomaterials, etc., water is sprinkled from a plurality of water sprinklers at the end. Since the water pressure of the water being sprinkled is made uniform by the pressure regulating valve, even if there are differences in height or distance between the multiple sprinklers, each sprinkler will always spray water under the same conditions.

〔Example〕

Preferred embodiments of the present invention will be described with reference to the drawings.

The system according to the present invention can be roughly divided into a pump, a filtration device,
It consists of an injection device for fertilizers, pesticides, etc., a valve device, a watering device, and a control device that controls each of the above devices.

In the figure, 11 is a pumping pipe, the tip of which is inserted into a water source 1 such as a pond, river, or water storage tank. A pump 12 is installed midway through the pumping pipe 1, and its operation increases the water source 1.
Water is pumped from.

The water pump 12 is controlled by a control device and operates to pump up as much water as necessary. The other end of the pumping pipe 11 is connected to the inlet side of the pump valve 13. An inflow side manifold 14 is connected to the outlet side of the pump valve 13. The inflow side manifold 14 branches into a plurality of parts, and each branch end is further divided into two parts via a backwash valve 15, one of which is connected to the upper part of the primary filter 16, and the other part is connected to the drain pipe 17. . - As the second filter I6, a gravel filter is usually used. −
A branch end of an outflow side branch pipe 18 is connected to the lower part of the secondary filter 16, and a secondary filter 19 is provided in the middle of each branch pipe 18a. As the secondary filter 19, a screen filter or a disk filter is usually used.

10 is an air release valve.

A main pipe 20 extends from the outflow side branch pipe 18, and a water meter 21 and a main valve 22 are installed in the middle thereof. The tip of the main pipe 20 branches into a plurality of pipes, and a water sprinkler 24 such as a sprinkler or a drip hose is attached to the tip of each branch pipe via a pressure regulating valve 23. FIG. 3 shows an example of the configuration of the pressure regulating valve 23. In the figure, 25 is a solenoid, which opens and closes the flow path based on an electric signal from a control device. A pilot 25a operates in response to the water pressure on the upstream side of the valve and functions to keep the water pressure on the downstream side constant. That is, if the water pressure on the upstream side is high, the pilot 25a
The P-boat and C-boat are opened, water pressure is applied to the bypass 26, and the diaphragm in the valve chamber is lowered to narrow the flow path. Conversely, when the water pressure on the upstream side is low, the P boat and S boat of the pilot 25a are opened, and a portion of the water is directly introduced into the downstream side through the bypass 27, thereby increasing the water pressure on the downstream side.

28 is a fertilizer pump driven by water pressure, and a water tube 29 whose one end is connected to the outlet branch pipe 18;
A fertilizer tube 31 extending from the fertilizer tank 30 and/or a biotube 33 extending from the biotank 32 are connected (see FIG. 1).

A solenoid valve 3 is installed at the connection part of the outflow side branch pipe 18 of the water tube 29.
4 is provided, and its operation draws the required amount of water into the fertilizer pump 28, thereby driving the fertilizer pump 28. The water used to drive the fertilizer pump 28 is discharged. Fertilizer tube 31 and bio tube 3
3 is equipped with a flow meter 35 and a solenoid valve 36 to check the amount of fertilizer, etc. supplied and to adjust the amount of fertilizer, etc. supplied. A fertilizer supply tube 37 is connected to the outflow side of the fertilizer pump 28 , and its tip is connected to the main pipe 20 via a fertilizer filter 38 and a solenoid valve 39 . In addition, the fertilizer pump 28 and the fertilizer tank 30
It is also possible to arrange the structure of the fertilizer injection device consisting of etc. in the watering section (see Figure 1).
Water, which is the driving source for the water supply device 8a, is taken from an appropriate location on the main pipe 20, and the fertilizer supply tube 37a is branched and connected to each watering device 24 individually. If necessary, the fertilizer injection equipment will be repositioned.

A differential pressure sensor 40 detects the difference between the water pressure in the inlet manifold 14 and the water pressure in the outlet branch pipe 18, and supplies the data to the computer.

To explain the operation of the above configuration, when the water pump 12 is activated and the pump valve 13 is opened based on a signal from the computer of the control device, water in the pond, water storage tank, etc.
Dirty water pumped up from 1 flows into the inlet manifold 14 from the pumping pipe 11 and is then branched off to the next filter 1.
6 (at this time, the flow path on the drain pipe 17 side of the backwash valve 15 is closed), the dirty water that enters the next filter 16 is filtered there, and then flows into the branch pipe 18a. The water enters the secondary filter 19 and is further purified by passing therethrough. A part of the water in the outflow manifold 18 flows into the fertilizer pump 28 through the magnetic valve 34 and the water tube 29, driving the fertilizer pump 28 to pump out the concentrated liquid fertilizer in the fertilizer tank 30. The pumped-out liquid fertilizer passes through the fertilizer supply tube 37,
After being filtered by the fertilizer filter 38, it flows into the main pipe 20 and is diluted with the water in the main pipe 20.

Then, after branching and being made to a constant pressure through each pressure regulating valve 23, water is sprinkled from each water sprinkler device 24. bio tank 32
On the other side, biomaterials and the like are supplied in the same manner as described above.

The filter in the above mechanism is automatically cleaned periodically or at appropriate times. In the illustrated example, automatic cleaning is performed by the action of a differential pressure sensor 400.

That is, when foreign matter accumulates in the filter and causes clogging, the outflow volume decreases relative to the inflow volume, the water pressure in the inflow side manifold 14 increases, and the water pressure in the outflow side manifold 18 decreases. . When the difference in water pressure between the two exceeds a set value, the backwash valves 15 operate in sequence based on signals from the computer, close the flow path on the inflow side manifold 14 side, and drain pipe 17
When the side flow path is opened, a portion of the water in the outflow side branch pipe 18 flows back into the filter 16, backwashing the filter.

As a result, the dust accumulated inside the filter is removed from the drain pipe 1.
7. Since this backwashing action is carried out sequentially in each secondary filter 16, the filter continues to perform its function for a long period of time without becoming clogged.

The backwash valve 15 may be operated every time a certain amount of water flows.

FIG. 4 is a system diagram of the control device, and 50 is a central computer, which includes a pump computer 51 that controls the operation of each pump, a weather station 52 that collects weather data and underground data, and controls water sprinkling. Each field unit computer of a plurality of irrigation computers 53 is connected, and the central computer 50 controls each of these field unit computers. The pump computer 51 includes a water meter,
Based on the data from the water pressure gauge and the water level needle, the operation of the water pump 12 and pump valve 13 is controlled to ensure that a predetermined amount of water is always supplied. In the example shown in Figure 4, water source 1
The water is pumped up into the water tank 54 by the water pump 12 and stored there at all times, and the amount of water to be sprayed is 224.
In this case, water in the water tank 54 is supplied by a water pump 55. The weather station 52 uses various sensors 56 placed at various locations to measure temperature, humidity, rainfall, wind speed, wind direction, as well as soil humidity, temperature, vapor,
Data such as electrical conductivity is collected and supplied to the central computer 50. These data are sequentially analyzed by the central computer 50, and each watering device starts and stops watering, and controls the amount of watering, etc., so that watering, fertilization, and medicine are always performed under optimal conditions. For example, watering is stopped when the wind speed is 5 m/sec or more or when it rains, and when the amount of rain exceeds 300 m/sec, the program changes to the corresponding program. The irrigation computer 53 uses the differential pressure sensor 40
The backwash valve 15 is controlled based on the information from the liquid fertilizer flow meter 35, and the solenoid valve 34 is controlled based on the information from the liquid fertilizer flow meter 35, thereby controlling the operation of the fertilizer pump 28. The main valve 22 is controlled based on the information.

In this manner, this apparatus is entirely monitored and controlled by computers centered around the central computer 50, and is configured to always perform optimal watering in accordance with the weather conditions and the conditions of the irrigated area.
